WebApr 2, 2024 · Applying Kirchhoff's current law, you can check it for yourselves. No matter your circuit and its operating conditions, the current going out of the battery should be equal to the current going in. The voltage only changes because the chemicals inside the cell are changed slightly and not because of a change in the number of electrons. WebOther articles where potential difference is discussed: analog computer: …mid-20th century operated by manipulating potential differences (voltages). Their basic component was an … WebVoltage is a measure of the energy carried by the charge . Strictly: voltage is the 'energy per unit charge'. The proper name for voltage is potential difference or p.d. for short, but this term is rarely used in electronics. Voltage is supplied by the battery (or power supply). Voltage is used up in components, but not in wires. ips nw birchwood

It only causes a current for a specific class of materials called conductors. For other materials, such as …

WebCurrent flows between two points that have a difference in electric potential, to balance this inequality. As the current flows between two points, every charge gains energy that is equal to the difference of potential between them. Two terminals of any battery have a potential difference between them, which is measured in volts.
